Summary
🤩
Rockstar🎓
Top SchoolDariusz Gafka is a Senior Software Engineer and architect with 11 years of experience designing message-driven, domain-centric systems and shipping production-grade PHP services. He runs Simply Coded Software, where he builds Ecotone to make DDD, CQRS and Event Sourcing practical in PHP, and currently contributes technical leadership at Lendable. His background spans high-throughput messaging platforms, Kubernetes deployments and event-sourced microservices for international clients, and he’s fixed core issues in well-known PHP projects like serializer and enqueue. Dariusz combines hands-on engineering—implementing DBAL fixes, union type support and constructor property promotion—with mentoring and consultancy to raise team capabilities. Based in Gdynia, he’s as comfortable authoring framework internals as he is optimizing large-scale integrations and operational observability. An uncommon strength is turning complex DDD/ES concepts into pragmatic, reproducible patterns that teams can adopt quickly.
